Claims.

This invention has to do with portable or mobile spraying equipment andit is a general object of the invention to provide spraying apparatusofsimple, practical form having a wide spread or covering capacity andcollapsible to render it operable through spaces or openings suitablefor passing ordinary vehicles.

Itis desirable in the spraying of crops or vegetation, generally, toprovide spraying apparatus `to be drawn by a tractor or the like, andwhich has avery wide spread, that is, which is considerably wider thanthe tractor in order to cover a wide path in the course of operation.Various devices vhave been proposed or provided for this class of useandcertain adjustments have been incorporated in such devices to vary theirwidth or extent. Generally speaking, spraying apparatus effective tocover a wide path is bulky, cumbersome, and difficult to manage, and isnot conveniently and readily operable through restricted openings orpassages, such as gates, narrow roads, etc.

` It is a general object of this` invention to providespraying apparatuswhich, when in operation, extends a substantial distance from eitherside of the draft vehicle and thus covers a very large path and which issuch that it can be easily and quickly collapsed or operated to a foldedor contracted position where it is no Wider than an ordinary vehicle,and consequently, can be passed through an ordinary `gate opening, alongan ordinary road, etc.

It isanother object of this inventionto provide spraying equipment ofthe general character referred to involving a frame carrying sprayheads, which frame is of simple practical dependable construction,involves few simple parts, and can be easily and quickly operatedbetween an extended position where it is of substantial length and acollapsed or folded position where it is of limited length.

It is another object of this invention to provide spraying equipment ofthe general character referred to including a simple practical andhighly effective mounting for supporting a frameor a carrier such as amobile tank, or the like. The present invention provides a mountingwhich supports a frame provided to carry spray heads, which mountingprovides for a general vertical adjustment of the frame through a widerange, and further, provides a means for trimming or leveling the frameso that it can be maintained `ina most advantageous position, or in anydesired position, about a horizontal axis transverse of the equipmentwhen adjusted to any vertical position.

. 2 u It is another object of this invention to provide sprayingequipment of the general char; acter referred to including a mountingforjsupa` porting `a frame and a simple,V practical and highly effectivemeans for trimming or leveling the frame so that the frame remainshorizontally disposed as the mounting means is operated vertically.

It is a` further object of the present invention to `provide sprayingequipment of the general character referred to including a frame, andaspray distributor carried by the frame `having spray heads in`connection `therewith such that there is free movement of the :frameand` free adjustment of the spray heads along the frame to gain anydesired lateral adjustment of the heads. i I It is a further objectofthe present invention to provide spraying equipment of the generalcharacter referred to involving a construction in which there is ashiftable nozzle carrying frame and simple, practical, and highlyeffective means for operating the frame from a point remote therefrom. i

The present invention provides or involves features of constructionapplicable to sprayers, t

generally, and the invention is intended to be carried out in apparatushandling various liquid sprays, powders, vor other like materials;Further, Athe inventionl contemplates the provision of V'app'arz'itus'of widely different capacity, that for handling a liquid spray and theconstructions set vforth are that which have been found tobecommercially practical for general use. t

-In the drawings lI have illustrated a movable carrier A involvingessentially a liquid carrying tank IU carried by a pair of vwheels Il.The carrier A is shown coupled to a suitable draft vehicle B in thenature of a tractor.

The form of the invention illustrated in Figs. 1 to 8 of the drawingsprovides, generally, a spray distributor C, spray supply means D, aframe E carrying the distributor C and mounting means F supporting theframe C from the carrier A. t t n A The spray distributor C vin theAform illustrated in the drawings involves a plurality oi heads l2 fromVwhich the spray is delivered, a

fsition's.

,4 of the invention being described it is shown as involving a main orcenter section X and two outer or end sections Y.

The mounting means F supporting' the frame E from the carrier Apreferably connects the frame with the tank il] and is operable so thatthe frame can be adjusted or shifted to various positions verticallyabove the ground over which the apparatus operates. The spraydistributor `C is characterized by a plurality or series of ,heads itand the manifold i3 so couples the heads as to enable them lto bearranged in various spaced relationships lengthwise of the trarne.Ordinarily, the several heads will be Aspaced. apart along the frame toform a series of heads extending the entire length of the frame as shownthroughout the drawings. However, it will be apparent that conditionssuch as the manner in which vegetation is planted in rows may reduireadjustment 'or spacing of the heads in a manner other than thatillustrated.

4Each head i2 involves an elongate tubular body mand a spray nozzle 2i'on one end of the body. In the case illustrated the other end of thebody is connected to a lateral branch or outlet 22 'of a tting 23 whichis a part of the manifold i3. It will be understood, of course, that thebody of the head may vary widely in form and construction, ascircumstances may require, and that the nozzle 2l may be of any suitableform or type serving to deliver spray inthe desired manner.

The bracket it provided in connection with each spray head preferablyinvolves'a saddle 25 iixed to one side ofthe body 2u of the head, iaclamp plate 2&3 Vand clamp bolts 2i connecting the plate to the saddle.rihe parts just described are shaped and proportioned to suitablycooperate with the frame part to which the bracket connects.I Where theframe part is a holder round in cross section, as shown in Fig. 7 of thedrawings, the saddle 25 is provided with a rounded seat 28 and is shapedto embrace the holder, while the clamp plate 26 may be a flat plateclosing the saddle and having its ends clamped to the ends of the saddleby the bolts 2i. Through this constructionv each head can be adjustedalong the holder oi the frame to the desired position, and if necessary,may be rotated on the holderto any desired rotative position thereon.

The manifold i3 of the spray distributor inv volves, generally, thettings 23 to which the bodies of lthe heads it are connected, andflexible couplings tl, which join or extend between adjacent fittings23. In practice the couplings il@ are flexible and may be `formed ofsuitable lengths of hose, or the like, the ends of which are suitablyconnected to the fittings 23, as clearly shown in Fig. '7 of thedrawings.

The frame E of the present invention, supported by the means F. normallyextends horizontally with its several sections aligned or arranged endto end as shown in Figs. 2 and 3 Where the frame involves a main orcenter section X and two end sections Y, it is preferred that the endsections Y be pivotally connected to the ends of the center section X,as by suitable pivot pins 33 and that the structure include stop means3A serving to limit downwardpivotal movement of the end sections Y sothat they stop in horizontal alignment with the center section when intheir lowermost po- Further, fastening means 35 are provided serving toreleasably fasten or hold the russes` end 'sectionsrY in a folded' orup'position,..such as is shown in Fig. lof the drawings.

The main or center section `X of the frame E is an elongate rigidstructure supported by themeans F so that itis maintained in ahorizontal position extending transversely of the structure. In the.form illustrated the main sectiorrXofi-the frame includes, generally,an upper longitudinal beam` 35, a lower `longitudinal front beam 31, endposts 38 that extend vvertically or substantially vertically at the endsof the frame section, and a head holder 39. The Vposts are shownextending between the upper beam` 36 and the head holder 39 so thatthese elements "arelconnected together at each end of the `frame sectionX. The lowefr beam 31 is shownlocated forward of and parallel 4.with theholder 39 and is coupled with the holder 35 at spaced pointsintermediate theends of the frame `sectionby spreaders 39B. `The pivot.pins `33 which support the end sections of the frame extend between theends of the holder 39 and the ends of the front beam 31 to which partsthey are rigidly connected, and thus, in effect, stiffen and becomeparts of the frame section.

The outer or end sections Y of `the frame are preferably alike and eachis shown as including a longitudinal head holder 4|), a lower forwardbeam 4| and an `upper beam 42. Each` end section of the frame furtherincludes a spreader Each end section is provided with stop means 34serving to stop it in a horizontal position upon being loweredtherethrough from an upright position such as is shown in Fig. 4. Thestop means involves a stop lug 50 projecting from the upwardlyprojecting standard at the inner or pivot- `ed endof frame sectionY,which lug is so arranged and disposed `as to bear outwardly against theinner edge or side of the post 38 of frame `section X occurring at theend of the frame section X towhich the frame section Y is pivoted. Itwill be apparent from the drawings that gravity serves to normally tendto swing or turn the Aend "frame section Y downwardly so that thestopflug A5|) remains in engagement with the post `3l? until the sectionY is deliberately swung or .lifted upwardly `as to a position such as isshown inFig. 4.

'Each endsecti'onY of `the frame is provided with a fastener` engageableto hold it in an up or elevated position, as shown in Fig. 4. Thefastener illustrated involves an extension 5| of ther-standardprojecting at the inner end of `the frame section Y to arpoint where itadjoins a stationary element of the lframe E when the parts `arepositioned, as shown in Fig. 4. In the arrangement illustrated theextension 5| is such as to adjoin or overlie a spreader 39 ci. framesection' X when the end section of the frame is up. The fastener furtherincludes a fastening device, preferably a releasable fastener, such as abolt 52, by which the extension 5| may be re- -leasably joined to thespreader 39 in a manner such as is shown in Figs. 4 and 8 of thedrawings. "The mounting means F supporting theframe E `from the carrierAA preferably couples the frame to the tank of'thebarrier, and in thepreferred the `invention illustrated in;Figs.V lm to o f Vthe drawings Iemploy a pair of .main mountingarms 10, and the means F includespivots1|` pivotally zontal transversezaxia L The arms 101supporttheframe E, as will` be hereinafter;describedfhand being pivoted to the`tankrl they s upport the frame so that it can be moved to;-var iouspositions vertically. f i s r `The means F includes iniadditionmto the i'adjustable fastening means` 1 5 inconnecton with the `arms l1liwherebyrthe armsA may be se;` cured or set inthedesired angularpositionnaubout` the' pivotal supports-1|; i In the form `oftl1e; irl4vention `under consideration there `isa unitn; means 15in connectionwith eacharm and each unit of the means415 includes an adjustingrod 1Bpivotally connected tothe farm 1 0 at 'l1-The rod 16 extends `through abracket `1 8 xed onthe` side 4of the tank l0` and adjusting nuts 1S `arethreaded on the rod 16` at either-side ofwthe bracket.

Ordinarily it is desirable to maintain theframe in what I term a perpendicularposi tion, that is, with parts suchas the posts 31 and standards 45 extending vertically so that the endsections of the frame swing up to trulyvertical positions upon beingfolded, as shown in Figa of the drawings. Y i L From theforegoingdescription `it, will be Y api parent that the center sectionof the frame ,E'

end sections of the frame from the extendedA working position shown inFigs. 2 and 3 to the up or folded position shown in Fig. 1i. The stopmeans 34 permit immediate movement of the end sections Y from theextended or working position, the means 35 are simple and effective andwhen the bolts 52 are engaged the end sections are securely maintainedin the up position. It will be apparent how theheads ci the spraydistributor may be spaced so they will serve to advantageouslydistribute spray, and it will be apparent that the flexible conductorsor elements 39 of the manifold i3, occurring where the sec-- tions ofthe frame are pivotally connected, allow for free pivotal movement yofthe end sections ofthe frame relative to the center section.Funthermore, it will be apparent how the supply line I6 of means D maycouple to the manifold i3 at any suitable point so that the means Ddelivers the desired spray material to the manifold for distribution tothe several heads l2.

The form of the invention illustrated in Figs. 9 t0 17 of the drawingsprovides, generally, the same broad or general elements or means asV setforth with reference to the form of the invention above described. lwill therefore' more briefly describe the second form of the inventionin light of the description applied to the first form.

The second form of the invention provides, generally, in addition to thecarrier A and draft vehicle B, a spray distributor C', spray supplymeans D', a frame E mounting means F', and an operatingor lifting meansG.

The spray distributor C' is essentially the same as the distributor Cfirst described and involves a plurality of heads l2', a manifold i3',and brackets lll'.` -In this form of the invention the brackets itprovided in connection with each spray head involves a pair of plates 25and 2e. Plate 25 is a xed plate extending laterally from the body 2li ofthe head, and may be secured to the body of the head as by welding. ltis preferred that the plate be pitched to extend somewhat axially of thebody, as well as laterally, as shown in Fig. 17.

Plate 26 is a movable plate extending laterally from the body 2d and isadjustable lengthwise of the body. Plate 26 is carried on the body abovethe plate 25 so that the spray head can be applied to a holder, suchasan elongate tubular member,v so that the holder is straddled or embracedby the two plates. In practice the plate 2li is provided with an openingEil somewhat larger than the body llt and when pressure is applied tothe outer end of the plate urging it toward plate 25 a positive grippingaction is established fixing the position of the plate lengthwise of thebody 2li.

A clamp bolt 2l' connects the outer endv portions of the plates 25 and26 and is operable to urge them toward each other establishing thedesired clamping pressure on the holder with the head in the desiredposition around and length- Wise thereof.

The supply means D is essentially the same as the means D firstdescribed and handles spray material received from tank lil of thecarrier A to deliver it tothe manifold I3 of the distributor 8. C".'Themeans D'` involves a pumping unit l5- and a supply line ill, all asabove described.

The frame E involves a main or center X and two outer sections Ypivotally connected to the ends of the center section.V Section Xincludes an upper beam 36, a lower beam 3l', end posts di?, and a headholder Sii. In this form of the invention the beam il is situatedforward of the holder Sii to occur below the beam 36', and the holder isspaced rearward of the beams 3l by spreaders 9i at the ends of the framesection X'.

Each outer section Y includes, a head holder de', a lower beam di', andan upper beam t2. In this form of the invention the holder li is at theforward side of the structure while the beam iii is at the rear thereof.The parts llt', di and ft2 converge throughout the length of the sectionand toward the outer or tip end thereof. At the inner end of eachsection Y' there is a spreader fifi spacing the beam lll and the holder,and there is a standard 35' which projects upward] to connect with thebeam ft2.

As shown in Figs. l5 and of the drawings spreaders ii' and @i cooperateto form a stop. The spreader dit abutts or seats against the spreader Siand the axis of the pivotal connection between the frame sections is asubstantial distance above the spreaders. A standard 92 projectsupwardly frorn the rear end of spreader Si and carries a pivot whichforms the pivotal connection between the sections at the rear of thestructure. A pivot 94 coaxial with pivot 93 forms the pivoted connectionbetween the sections at the front of the structure. Pivot 94 is carriedby the standard llt and engages the forward side of the section Y. Abrace member 95 is provided at the inner end of the section Y betweenupper beams d2.' and the holder dll.

When the outer sections are down or extended the parts lii and iii abuttproviding a stop to hold the outer sections in true alignment with thecenter section.

The form of the invention illustrated in Figs. Q to 17 ofthe drawingincludes lifting or operating means G for the outer sections of theframe. The means G in its preferred form involves generally flexiblelines @il extending from the outer sections of the frame to the vehicleB to be manipulated by the operator thereof. A line dii is secured toeach outer frame section at ill and passes over a pulley SS supported attheV upper end portion of a standard 38. Line 9G, is shown passing overa second pulley 9S suitably locatedon the frame E from which it extendsto the vehicle B. By suitable handling of lines the operator. maycontrol the positions of the rame extensions Y from the drivers seat. ofthe vehicle B.

Each frame section Y isk provided with a fastener 35' engageableto'releasably hold it in an up or elevated position. A brace iilil isprovided at each end of frame section X and extends diagonally from therear end of spreader Si to the beam 36. The fastener 3E is shown carriedby the brace itt to occur near the upper or head end portion of standardlib. The fastener involves a hook 52 secured to the lbrace through Aaspring 53'. A suitable fastening bar Mii is carried at the head of thestandard d5 to cooperate with the hook 52. When the section Y iselevated to the position shown at the right in Fig. ll,

bar so that the standard 45 is heldl down tight against the brace |00,as indicated by the broken lines in Fig. `14 of the drawings.

The mounting means li"` illustrated in Figs. 9

, to 17 of the drawings mounts the frame forvertical adjustment and actsto turn or level the frame E' so that the frame remains horizontallydisposed as it is bodily adjusted vertically. The means F involves,generally, one or more main arms IIU andone or more stabilizing armslll. In the case illustrated the arms HI are arranged or located abovethe main arms `l ID. The arms IIB and III are parallel, are of equallength and are preferably spaced a substantial distance apartvertically. In the preferred form of the invention the arms I Ill and il l are pivotally connected at their inner ends to the. rear of the tankl of the carrier A, and at their outer ends to the frame E. The pivotalconnections H2 at the tank are in spaced vertical alignment, while thepivotal connections H3 at the frame E are in like or correspondingspaced vertical alignment. Since the connections I I2 at the tank arefixed and in vertical alignment the connections H3 at the frame remainin vertical alignment reardless of the position to which the frame maybe adjusted vertically.

The invention provides adjustable fastening means in connection with thearms IHJ and Ill whereby the arms may be supported in any desiredposition. In the drawings the means 'l5' is shown as involving one ormore adjusting bars pivotally secured to the upper rear end portion ofthe tank I0. Each bar has an elongate series of openings l22 to beselectively employed to register with an opening in the lower or mainarm IID. A pin I2! or the like, is engaged in the lgistering Openings tosecure the structure in the desired position.

The invention has been described as being employed for sprayingvegetation over which the frame is operated, that is, it has beenimplied that the structure is to be used for spraying close to theground. It is to be understood that the invention is not to be construedas limited to this particular use, since it may be varied widely in useor application. For example, if tall or upstanding vegetation, such astrees are to be sprayed such action can be gained by operating theapparatus with the end sections or with an end section of the frameprojecting upwardly in the desired manner, as for instance, vertically,as shown in Fig. e. In such case the spray heads of the spraydistributor will, of course, be suitably arranged and distributed andmay even be confined solely to the end sections of the frame, or to theparts thereof, all as circumstances may ren quire.
